In this study, a semianalytical method for the design of mutual coupling free multiband matching networks is introduced. A new parametric representation of Brune functions is used for the construction of multiband ladder network topologies without mutual induction. The method involves the use of Fujisawa's constraints for low pass ladders having finite transmission zeros, in a parametric representation of driving point impedance function resulting in mutual inductance free Brune sections. The developed parametric representation is incorporated with Real Frequency Techniques to design matching networks with a plurality of pass bands. Several illustrative design examples are presented to validate the method.

使用Brune函数的参数表示设计无互耦的多频带匹配梯形图

在这项研究中，介绍了一种用于互不耦合多频带匹配网络设计的半解析方法。Brune函数的一种新的参数表示形式被用于构建不带互感的多频带梯形网络拓扑。该方法涉及对具有有限的传输零点的低通梯子使用藤泽约束，以驱动点阻抗函数的参数表示形式产生互感自由的Brune部分。将开发的参数表示与Real Frequency Technologies结合使用，以设计具有多个通带的匹配网络。给出了几个说明性的设计实例来验证该方法。
